BODY-BOLSTER.

SIPIECIFICATION forming part of Letters Patent No. 717,386, dated December 30 1902.

Application filed .Tune 30, 1902. Serial No. 113.693. (No model.)

To a/Z whom/t may concern:

Be it known that we, JAMES H. GEER and.

DAVID WISOR, citizens of the United States, residing at Johnstown, in the county of Cambria and State of Pennsylvania, haveinvented certain new and useful Improvements in Body-Bolsters; andwe do Vhereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Our invention consists of various improved constructions of car-holsters and the details thereof, with particular reference to those known as body-bolsters. Y

Certain ofthe objects of our invention are to produce a structure well adapted to withstand the various stresses to which it issubjected in use, simple, cheap, and,k formed ofmaterials easily obtained and manufactured.

We will new in order to make `the matter more clear refer to the annexed sheet of drawings,which form partofthis specification, and in which like figures refer to like parts.

Figure 1 is a plan of our bolster. Fig. 2 is a side elevation thereof. Fig. 3 is a central vertical sectional elevation on the line A A of Fig. 2. Fig. 4. is alvertical sectional elevation on the line BB of Fig. 2. Fig. 5 is a vertical sectional elevation on the line C C of Fig. 2.

Referring now to the various characters of reference upon the drawings, l is part of the top member, shown of channel-section. 2 is a fiat plate rivetedto the web thereof and projecting outwardly therefrom. 3 represents narrow reinforcing-plates or flat bars secured to the under side of said plate on each side of the channel-flanges, as shown. Y

4 is the lower or compression membeigshown as a heavy bar, secured to the ends of the top. or tension member and separated therefrom at the center by a center strut 5, which con" the upper plate in places where the longitu dinal sills of the car will rest.

6 is a center bearing, (shown in this case as a casting,) which may be of any form desired.

7' represents the posts, which in connection' with the middle support 5 serve` to separate thelower member or bar 4. from the upper member of the bolster as Well as give strength and rigidityrto that'part of the structure. They are shown as consisting of hollow flat castings having parallel walls between which through-bolts pass to secure them and the upperv and lower members of the bolster together. Said posts 7 have their lower parts arranged to project over the sides of the bottom member 4:, and' thus confine it laterally as well as vertically, besides which these posts 7 and the middle support 5 are in turn convlined at their upper extremities between the depending flanges of the channel 1.

8 represents intermediate posts or sleeves of link shape secured by through-rivets between the upper member and the inclined part of the lower member of the bolster, as shown. These posts or sleeves serve to give increased strength and rigidity to the ends of our` bolster and are very efficient, owing to the link shape above mentioned,which makes the rivets or-bolts cooperate, giving lateral stiness to the structure, and thus increasing the efficiency of the whole.

Although we have shown our improvements in considerable detail, we do not limit ourselves to the exact particulars of construction and arrangement as herein described and illustrated, but may use such variations and modications or equivalents thereof as are embraced within the scope of our invention and as pointed out in the claims.

Having thus given a description of our invention, what We claim, and desire to secure by LettersPatent, is-

1. 1n a car-bolster of trussed construction, a top memb'er composed of a rolled channel with dependent flanges, a plate riveted to and throughout the length ofthe top of the web of said channel and projecting sidewise beyond the channel-danges, a reinforcingbar secured to the under side of said projections on each side of said channel member, a bottom member consisting of a flat bar secured to the ends of said top member, and a center strut secured between the middle portions of said top and bottom members.

2. In a car-bolster, a top member composed of a rolled channel with depending flanges, a plate riveted to and throughout the length of the top of the web portion of said channel, a bottom or compression member consisting of a flat bar secured to the ends of said top member, and a center strut secured between the middle portions of said top and bottom members.

3. In a car-bolster, an upper member composed of a rolled channel with its flanges extending downwardly and a plate riveted to and extending throughout the length of the top of the web of said channel members.

4. In a car-bolster, an upper member composed of a rolled channel with its flanges extending downwardly, a plate riveted to and extending throughout the length of the top of the web of said channel member and extending outwardly sidewise therefrom.

5. In a car-bolster, a top member composed of a rolled channel with dependent flanges, a plate of thesame length riveted to the top of the channel member and projecting outwardly sidewise therefrom, reinforcing-bars secured to the bottoms of the projections on each side of said channel member.

6. In a car-bolster of trussed construction, a top member composed of a channel with dependent flanges, a plate riveted to and throughout the length of the top of the web of said channel member, a bottom member consisting of a flat bar secured to the ends of said top member, and a center strut located between and secured to said top and bottom members at the middle portions thereof.

7. In a car-bolster, a top member comprising a rolled channel with dependent flanges, a plate riveted to and throughout the length of the top of the web portion of said channel member, a bottom member consisting of a flat bar secured thereto at its ends and separated therefrom by a center strut composed of a hollow four-.sided casting having parallel walls and outwardly-extending flanges secured to and between the middle portions of the top and bottom members aforesaid.

8. In a car-bolster, a top member comprising a channel with dependent flanges, a plate riveted to the web portion of said channel member and extending outwardly therefrom, a bottom member consisting of a flat bar secured to said top member at its ends and separated therefrom at its middle portion by a center strut composed of a hollow four-sided casting having parallel walls and outwardlyextending flanges secured to and between said top and bottom members.

9.
